#1772 ./flow -gui crashing with segfault Issue created by mattvenn Description After hardening a design with openlane:

./flow.tcl -design spm

I try to open the gui (which worked about a month ago):

./flow.tcl -design spm -tag RUN_2023.04.26_09.09.28 -gui

And get a segfault. Expected Behavior The GUI should open Environment report
